Build an array from source and pass to script

[Moriarty]

The title says it all, I'm making a function to return char_ids from everybody on the player screen, so I need to build an array from source, so I can use it on my script, but I have no idea how to do it

For examples, look at script commands that set global arrays.

getpartymember() - src/map/script.c#L7142

		for(i=0;i<MAX_PARTY;i++){
			if(p->party.member[i].account_id){
				switch (type) {
				case 2:
					mapreg_setreg(reference_uid(add_str("$@partymemberaid"), j),p->party.member[i].account_id);
					break;
				case 1:
					mapreg_setreg(reference_uid(add_str("$@partymembercid"), j),p->party.member[i].char_id);
					break;
				default:
					mapreg_setregstr(reference_uid(add_str("$@partymembername$"), j),p->party.member[i].name);
				}
				j++;
			}
		}

Thanks, I did it before looking here, this was a silly post, I should have searched

 

Anyway, I have a new problem now.
How do I delete all elements of this array before build it?

I was using mapreg, now i'm using pc_setreg and deleting the array with the npc.. It works, but it would be nice to know how to do it from source :\

Looking at src/map/mapreg_sql.c#L36, it automatically removes/deletes the variable if you are setting it to 0 or "".
